A remote attacker could exploit some of these vulnerabilities to trigger denial of service condition, elevation of privilege, remote code execution, sensitive information disclosure, data manipulation and security restriction bypass on the targeted system.

Impact

Denial of Service
Remote Code Execution
Information Disclosure
Elevation of Privilege
Data Manipulation
Security Restriction Bypass

System / Technologies affected

Ubuntu 20.04 LTS
Oracle Linux 7
Oracle Linux 8

Solutions

Before installation of the software, please visit the vendor web-site for more details.

For Ubuntu

The problem can be corrected by updating your system to the following package versions:

Ubuntu 20.04 LTS
- linux-image-5.14.0-1022-oem - 5.14.0-1022.24
  linux-image-oem-20.04d - 5.14.0.1022.19

After a standard system update you need to reboot your computer to make all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.

For Oracle Linux
